Abstract

Un dispositivo indicador de tiempo y temperatura provee una indicacion visualmente observable de la exposicion térmica acumulada de un objeto. Eldispositivo incluye un sustrato con una matriz porosa que refleja difusamente la luz y un soporte. El soporte incluye sobre su superficie un material indicadorviscoelástico para tomar contacto con el sustrato y un material de barrera par inhibir sustancialmente el flujo lateral de material indicador viscoelásticoentre el sustrato y el soporte.A time and temperature indicating device provides a visually observable indication of the cumulative thermal exposure of an object. The device includes a substrate with a porous matrix that diffusely reflects light and a support. The support includes on its surface a viscoelastic indicator material to make contact with the substrate and a barrier material to substantially inhibit the lateral flow of viscoelastic indicator material between the substrate and the support.
